Disclosure: As an Amazon Associate I earn from qualifying purchases, yet this 2026 comparison of the best price tracker tools remains fully independent and honest, offering
If you’ve ever bought something on Amazon the day before it dropped 20%, you already know why a price tracker earns a permanent spot in your browser bar. The two names that come up every time this topic gets discussed are CamelCamelCamel and Keepa — both free to start, both pulling from years of price-history data, and both doing genuinely different jobs once you look past the marketing.
This guide compares the two head-to-head, plus where PayPal Honey fits in (and where it doesn’t), so you know which one to install before your next big purchase.
CamelCamelCamel: the free, no-nonsense option
CamelCamelCamel has been tracking Amazon prices since 2008 and is entirely ad- and affiliate-funded — there’s no premium tier, no paywall, no “upgrade to see the full chart.” Every product page shows three price lines (Amazon, third-party new, third-party used) plotted over time, along with the all-time high, low, and average. Charts typically go back six months or more, sometimes years for long-running products.
Its Camelizer browser extension (Chrome, Firefox, Edge, Safari) overlays the price history directly on the Amazon product page, so you don’t have to copy-paste URLs back and forth. Create a free account and you can set price watches that email you the moment a product hits your target price, and import your Amazon wishlist so it tracks everything on it automatically.
Coverage extends to about eight Amazon marketplaces (US, UK, Canada, France, Germany, Italy, Spain, Japan). A sister site, CamelMart, does the same thing for Walmart.
Where it falls short: the free/ad-funded model means the interface looks dated, and alerts are email-only — no push notifications, no Telegram, no SMS. It also only tracks products, not sellers or categories, which matters if you’re doing sourcing research rather than personal shopping.
A practical way to use it: before adding anything over around $30–40 to your cart, paste the product URL into the CamelCamelCamel search bar (or click the Camelizer icon if you have the extension installed) and glance at the six-month chart. If today’s price sits at or near the all-time low, buy. If it’s near the all-time high, the “limited time deal” badge Amazon slapped on it is doing more work than the actual discount.
Keepa: deeper data, and a real price tag if you want more
Keepa covers more ground — price history across 11+ Amazon marketplaces and a claimed 3+ billion tracked products — and its browser extension (Chrome, Firefox) embeds a denser chart directly on the product page, including Buy Box price, sales rank history, and Lightning Deal tracking.
The free plan lets you track up to 5,000 products, view full price history charts, and set alerts through the extension at no cost. Where Keepa splits from CamelCamelCamel is the paid tier: a Keepa subscription (roughly $15–29/month depending on plan and billing cycle) unlocks alert delivery via push notification, Telegram, or Facebook Messenger instead of just email, plus tools aimed squarely at Amazon sellers — Product Finder, Category Tree browsing, Seller Lookup, and Top Seller lists. There’s also a separate Keepa API subscription (starting around €49) for developers pulling price data programmatically.
Where it falls short: most of what justifies the paid tier — seller research tools, faster alert channels — is overkill if you’re just trying to catch a good price on a laptop. The free plan covers everything a casual shopper needs; the subscription is really built for resellers and Amazon sellers doing competitive research.
Keepa’s sales-rank chart is the feature CamelCamelCamel doesn’t have an equivalent for, and it’s genuinely useful beyond reselling: a rank history that spikes and crashes tells you a product had a short-lived promotion or went viral, versus a steady rank that suggests consistent, real demand. If you’re trying to judge whether a product is a fad or a long-term staple before buying into an ecosystem (accessories, replacement parts, subscriptions), that chart is worth checking even on the free plan.
Where PayPal Honey fits (and doesn’t)
Honey (now owned by PayPal) gets lumped into this conversation because it’s the most-installed shopping extension by a wide margin, but it’s solving a different problem: automatic coupon-code testing at checkout, not historical price tracking. Its “Price History” feature exists but is thinner than CamelCamelCamel’s or Keepa’s — shorter lookback windows, fewer marketplaces, no email price-watch alerts on Amazon specifically. Install Honey for coupon-hunting at checkout; don’t rely on it as your price-history tool.
Comparison table
| Tool | Cost | Price history depth | Alert channels | Best for |
|---|---|---|---|---|
| CamelCamelCamel | Free | 6+ months, 3 price lines (Amazon/new/used) | Email only | Casual shoppers wanting a simple watch-and-wait tool |
| Keepa | Free (5,000 products); Pro ~$15–29/mo | Deeper, longer history + Buy Box + sales rank | Push, Telegram, Messenger, email (paid tiers) | Frequent buyers and resellers who want faster alerts or seller data |
| PayPal Honey | Free | Shallow, secondary feature | None specific to price-watch | Coupon code testing at checkout, not price tracking |
Verdict: which should you actually install?
If you buy on Amazon occasionally and just want to know “is this actually a good price,” install CamelCamelCamel’s Camelizer extension and call it done — it’s free forever and answers the question in one glance. If you’re a frequent enough buyer that email-only alerts feel too slow, or you’re doing any kind of Amazon selling or sourcing, Keepa’s free tier (or its paid plan if you need push alerts) gives you meaningfully more data. Most readers don’t need both — pick CamelCamelCamel first, and only add Keepa if you outgrow it.
FAQ
Is CamelCamelCamel actually free, no catch?
Yes. It’s funded by ads and Amazon affiliate commissions on the products people track, not by a subscription. All core features — charts, watches, wishlist import — are free.
Does Keepa work on non-Amazon sites?
No, Keepa is Amazon-specific across its 11+ regional marketplaces. It doesn’t track Walmart, Target, or other retailers.
Can these tools guarantee I get the lowest possible price?
No tool can guarantee that — they show historical patterns, not future predictions. What they reliably do is stop you from mistaking a fake “was” price for a real discount, since you can see the actual price the item sold at over recent months.
Do I need an account to use either tool?
CamelCamelCamel requires a free account only for price watches and wishlist import; browsing price history needs no account. Keepa’s browser extension works without an account for basic charts; alerts and the 5,000-product tracking limit require a free sign-up.
